Re: i915 backlight

Hello,

I am using a Lenovo Edge E530 and, with kernel 3.11.0-rc3, I had to
change to this parameter to the kernel boot:


GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\""


instead of previous

GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"

to be able to change brightness. In some kernel versions before, it
worked, but with 15 levels, but in graphical system brightness bar was
not moving.


Now I have, though, 8 possible values for brightness and brightness
bar shows its correct position.
